چکیده
Pedagogical agent research seeks to exploit Reeves and Nass’s Media Equation theory, which holds that users respond to interactive media as if they were social actors. Investigations have tended to focus on the media used to realize the pedagogical agent, e.g., the use of animated talking heads and voices, and the results have been mixed. This paper focuses instead on the manner in which a pedagogical agent communicates with learners, i.e., on the extent to which it exhibits social intelligence. A model of socially intelligent tutorial dialog was developed based on politeness theory, and implemented in an agent interface within an online learning system called Virtual Factory Teaching System. A series of Wizard-of-Oz studies was conducted in which subjects either received polite tutorial feedback that promotes learner face and mitigates face threat, or received direct feedback that disregards learner face. The polite version yielded better learning outcomes, and the effect was amplified in learners who expressed a preference for indirect feedback, who had less computer experience, and who lacked engineering backgrounds. These results confirm the hypothesis that learners tend to respond to pedagogical agents as social actors, and suggest that research should focus less on the media in which agents are realized, and place more emphasis on the agent’s social intelligence.

The Politeness Effect in an Intelligent Foreign Language Tutoring System
A previous study showed that pedagogical agents that offer feedback with appropriate politeness strategies can help students learn better [21]. This work studied the Politeness Effect in a foreign language intelligent tutoring system, and provided further evidence that tutorial feedback with socially intelligent strategies can influence motivation and learning outcomes.

Recent research on conversational agents emphasises the need to build affective conversational systems with social intelligence. Politeness is an integral part of socially appropriate and affective conversational behaviour, e.g. consider the difference in the pragmatic effect of realizing the same communicative goal with either “Get me a glass of water mate!” or “I wonder if I could possibly ha...
